PAPER BAG.

Application filed July 28,

To all whom it may concern: v

Be it known that I, ADoLPH Po'rDEvIN, a citizen of the United States, and resident of the city of New York, borough of Brooklyn in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Paper Bags, of which the following is a specification.

The object of this invention is to provide a paper bag having at its open end a foldable closure flap embodying carrying and locking means of simple, inexpensive and h efiicient construction.

According to my inventlon I form in the front and back of the bag, adjacent the. flap,

suitable apertures in alinement with each other, and 1 form directly in the flap a. tongue which is so positioned that when the flap is folded to close the bag, thetongue can be readily flexed through said apertures from one side of the bag and then folded on the reverse side of the bag in such a manner as not only to lock the flap in place but also to reinforce and strengthen the upper edge of the bag; the space produced by the formation and folding of the tongue being in reg.- ister with the'said apertures and affording therewith an efficient finger opening or handle to facilitate the carrying of the bag; all as will be hereinafter described and claimed.

In the drawings-7 I Figure 1 is a back view of a p'aper bag embodying a form of my invention.

Fig. 2 is a perspectlve View, from the front, of the upper or open end of the bag.

Figs. 3 and 4 are perspective views, from the front andback respectively, showing the flap as closed and locked.

Fig. 5 is a vertical section, enlarged, on the line 5-5 of Fig. 4.

Figs. 6 and 7 illustrate back views of the upper end of a bag embodying a slight modification of the features of the invention, showing the closure flap as unlocked and locked respectively.

Figs. 8 and 9 are similar views of another modified structure with the closure flap as unlocked and locked respectively.

Figs. 10 and 11 are similar views of still Fig. 12 is a view of the structure shown in Figs. 10 and 11, but with the flap open in order to "indicate more clearly the tongues 1921. Serial N0. 488,159.

within the apertures of the back and front of the bag.

a To IPOTDEVINI' -MACHI1\l'Il COMPANY,

The type of paper bag herein selected to illustrate my invention comprises a front and a back 10, 11, respectively; a closed end 12, and an open end 13, the front being extended beyond the 0 en end to rovide a fold able closure flap I4. p

In the present instance the blank from which the folded to present a rectangular receptacle aving a median longitudinal seam 15 on the back; but so far as my invention is concerned the particular form of the bag or the position of the seam is not essential.

In the construction shown in Figs. 1 to 5, inclusive, there areformed in the front andback of the bag, adjacent its open end and in alinement with each other, two corresponding apertures 16 which are of such dimensions as to permit the forefinger of a person to be passed freely therethrough. These apertures are so disposed in relation to the flap 14 that when the flap is folded over, and upon the back of the bag it overlaps the plane of the apertures. 17 iscut directly from the material constituting the flap and is so located that the hole, 18, thus produced, bounds the aperture 16 in the back of the bag when the flap is folded as above mentioned. The ends of tongue are preferably rounded and extended beyond the respective ends of the adjacentaperture 16 so as to provide flexible locking members 19, and the line of connection '20 of the tongue with the body of the flap is adjacent the basal fold line of the latter. Hence when the flap is folded over and upon the back of the bag the tongue with its flexible end members can be readily bent through the apertures 16, which members thereupon resume their outward position beyond the ends of the apertures and thus prevent the accidental return'and release of the tonguef Such tongue when it is interlocked with the apertures 16 is folded upward against the upper front portion of the bag, as shown in Figs. 3, 41 and 5. By this construction it will be seen that the space produced by the formation and folding of the tongue, plus the apertures inthe front and back of the bag, affords an efficient finger opening or handle to facilitate the carrying of the bag, and that the folded tongue with its projecting ends not only res bag is constructed is shaped and A tongue 'diiferent shapethan in the first described construction, and the tongue 17 of the flap instead of being formed with end extensions,

is simply made slightly longer than the apertures, asat 17 i In the construction'shown-in Figs 8 and 9, the apertures 16 and the tongue 17 are made in the form of reversed truncated triangles respectively. f

In the construction shown in Figs. 10, 11 and 12, each of the apertures 16 is provided with a tongue 16, the two tongues being foldable with the tongue 17 of the fia and. such latter tongue being extended ad acent the ends of the fold line, as at 17 so as to form flexible locking members.

In each of the constructions hereinbefore described the co-related tongue, or tongues, and apertures may be formed in the ma terial after the blank has been folded and made into bag form, or such tongue, or tongues, and apertures may first be formed in the blank.

My invention is not limited to the specific constructions herein disclosed as the same may be modified within the principle of the invention and the scope of the appended claims. j

I claim 1. A paper bag comprising aback, a front, and a foldable closure flap, said back and front having registering finger apertures extending therethrough adjacent the flap, and

said flap having a locking and reinforcing tongue so arranged that when the flap is folded the tongue can be flexed through said apertures from one side of the bag and folded upward on the opposite side of the bag, said tongue being cut from' the body of the flap to provide in the latter an opening registering with the said apertures, and said tongue being proportioned relatively to the apertures to present a free edge portion which projects beyond the adjacent edge of the apertures when the flap is initially folded, and thus provides a locking member for the tongue When it is flexed through the apertures.

2. A paper bag comprising a back, a front, and a foldable closure flap, said back and front having registering finger apertures exf tendingtherethrough adjacent the fiap, and said flap having-a tongue s'o arranged that when'the flap is folded the tongue can be flexed through said apertures from one side of the bag and folded upward on the opposite side of the bag, said tongue having locking extensions beyond the adjacent ends of the said apertures and being cut from the body of the flap to provide in the latter an opening registering with said apertures.

3. A paper bag comprising a back, a front, and a foldable closure flap, said back and front having registering finger apertures extending therethrough adjacent the flap, and said flap having a tongue so arranged that when the flap is folded the tongue can be flexed through said apertures from one side of the bag and folded upward on the opthe latter an opening registering with said apertures.
